JET A / JP54

COMMERCIAL JET FUEL

 

JET A

Jet A specification fuel has been used in the United States since the 1950s and is usually not available outside the United States and a few Canadian airports such as Toronto and Vancouver, whereas Jet A-1 is the standard specification fuel used in the rest of the world other than the former Soviet states where TS-1 is the most common standard. Both Jet A and Jet A-1 have a flash point higher than 38 °C (100 °F), with an autoignition temperature of 210 °C (410 °F).


DIFFERENCES BETWEEN JET A AND JET A-1

The primary difference is the lower freezing point of A-1:

  • Jet A's is −40 °C (−40 °F)
  • Jet A-1's is −47 °C (−53°F)

The other difference is the mandatory addition of an anti-static additive to Jet A-1.

Jet A trucks, storage tanks, and plumbing that carry Jet A are marked with a black sticker with "Jet A" in white printed on it, adjacent to another black stripe.



Typical physical properties for Jet A and Jet A-1

Jet A-1 fuel must meet:

  • DEF STAN 91-91 (Jet A-1),
  • ASTM specification D1655 (Jet A-1), and
  • IATA Guidance Material (Kerosene Type), NATO Code F-35.

Jet A fuel must reach ASTM specification D1655 (Jet A)
